【问题描述】：

我正在使用全屏大小的初始屏幕，没有操作栏布局，但是当我移动到登录活动时，这是具有操作栏的正常活动，我的布局不能顺利移动，它显示一些闪烁（上/下）。我不是克服它请帮助...

我正在使用 Intent 将动作从启动活动传递到登录活动

这是我的启动画面代码：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);
        /* set time to splash out */
        final int welcomeScreenDisplay = 4000;
        /* create a thread to show splash up to splash time */
        Thread welcomeThread = new Thread() {
            int wait = 0;

            @Override
            public void run() {
                try {
                    super.run();
                    /*
                     * use while to get the splash time. Use sleep() to increase
                     * the wait variable for every 100L.
                     */
                    while (wait < welcomeScreenDisplay) {
                        sleep(100);
                        wait += 100;
                    }
                } catch (Exception e) {
                    System.out.println("EXc=" + e);
                } finally {
                    /*
                     * Called after splash times up. Do some action after splash
                     * times up. Here we moved to another main activity class
                     */
                    startActivity(new Intent(SplashActivity.this,
                            LoginActivity.class));
                    finish();
                }
            }
        };
        welcomeThread.start();
    }
}

你能把你的启动活动的代码贴出来
我已经在这里发布了启动活动代码

标签： android layout screen splash-screen

【解决方案1】：

使用它来创建延迟

/** Duration of wait **/
    private final int SPLASH_DISPLAY_LENGTH = 1000;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.splashscreen);

        /* New Handler to start the Menu-Activity 
         * and close this Splash-Screen after some seconds.*/
        new Handler().postDelayed(new Runnable(){
            @Override
            public void run() {
                /* Create an Intent that will start the Menu-Activity. */
                Intent mainIntent = new Intent(Splash.this,Menu.class);
                Splash.this.startActivity(mainIntent);
                Splash.this.finish();
            }
        }, SPLASH_DISPLAY_LENGTH);
    }

感谢您的回复，但这对我没有帮助。您认为动画可能是解决此问题的一种方法

【解决方案2】：

以

身份启动您的活动

new Handler().postDelayed(new Runnable(){
            @Override
            public void run() {
                /* Create an Intent that will start the Menu-Activity. */
                Intent mainIntent = new Intent(Splash.this,Menu.class);
                mainIntent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                Splash.this.startActivity(mainIntent);
                Splash.this.overridePendingTransition(0,0);
                Splash.this.finish();
            }
        }, SPLASH_DISPLAY_LENGTH);

它解决了你的问题。

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

    startActivity(new Intent(SplashActivity.this,LoginActivity.class));

    // for activity animation.
    //overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
    finish();
